Disable ng-click on certain conditions of applicat

问题:

In my application I've binded several elements with ng-click directive like below

<a ng-click="DoSomething()"/>
<button ng-click="DoSomethingElse()">xyz</button>
<span ng-click="DoSomething()"></span>

Now in my application in certain scenarios I want default behavior of ng-click to happen, but in certain scenarios I want to completely disable the callback function(DoSomething(), DoSomethingElse()..) to be called..

For checking this scenarios I've one scope variable say $scope.IsClickEnable = true/false;

So how can I accomplish this kind of behaviour?

I can use ng-disable to disable elements but it will only work on button kind of elements, so that will not work in my scenario

And I can also check conditions in every function call but I want more specific way to accomplish this by overriding ng-click behavior or something..

Do like this:

<button ng-click="!IsClickEnable||DoSomethingElse()">xyz</button>

when the value of IsClickEnable is true then the function will be called on the button click then the function 'DoSomethingElse()' will be called else it will not get called
